LM2902 产品概述
一、产品简介
LM2902 是萨科微（Slkor）推出的一款四路运算放大器，针对工业级应用设计，兼顾低噪声、低功耗与宽电源电压范围。该器件在单片内集成四个放大通道，适合多路信号调理、传感器接口与低频模拟处理场景。
二、主要参数
- 放大器数：4路
- 最大电源宽度 (Vdd–Vss)：32 V
- 单电源工作范围：3 V ~ 30 V
- 双电源对称范围：±1.5 V ~ ±15 V（对应 -15 V ~ -1.5 V / 1.5 V ~ 15 V）
- 增益带宽积（GBP）：1.3 MHz
- 压摆率（SR）：0.4 V/µs（400 V/ms）
- 输入失调电压（Vos）：7 mV，温漂 30 µV/℃
- 输入偏置电流（Ib）：300 nA，输入失调电流（Ios）：2 nA，Ios 温漂 10 pA/℃
- 噪声密度：40 nV/√Hz @1 kHz
- 共模抑制比（CMRR）：80 dB
- 静态电流（Iq）：700 µA
- 输出电流能力：40 mA
- 工作温度：-40 ℃ ~ +125 ℃
- 封装：SOP-14
三、典型应用
- 传感器信号放大与滤波（温度、压力、位移等）
- 仪表放大器前端与差分信号调理
- 低速采样的信号链路（数据采集、ADC 缓冲）
- 工业控制、家电控制与电源监测电路
四、设计与使用建议
- 电源去耦：建议在电源引脚并联 0.1 µF 陶瓷与 10 µF 电解电容，以抑制高频与低频干扰。
- 输入保护：若输入有大幅度共模或快速瞬态，建议增加限流电阻或钳位二极管保护放大器输入。
- 布局注意：模拟地应短回路并靠近器件地脚，敏感输入线避免与开关信号平行走线。
- 带宽与负载：GBP 1.3 MHz 与 0.4 V/µs 压摆率限制高频与快速边沿性能，适用于低频至中频信号处理；驱动大容性负载时应避免振荡并检查稳定性。
五、封装与采购
LM2902 提供 SOP-14 封装，适合批量贴片生产。萨科微（Slkor）品牌，适用于工业等级温度范围内的长期可靠运行。购买时请根据应用场景确认温度等级与批号，并参考器件典型特性曲线进行电路仿真与验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
